The nine-square-metre mobile home was designed by Hristina Hristova as a more affordable and flexible alternative to a fixed holiday house. She named it Koleliba, an amalgamation of the Bulgarian words for hut and wheel, and spent €8,500.

The hut has an internal ceiling height of 2.4 metres, similar to the height of a standard room, and contains a sofa bed, a kitchen and a toilet at one end, which is separated by a plywood door added after the photographs were taken.

“Unlike lacquer, which mainly aims to entirely seal the surface of the wood, the oil infiltrates the timber fibres, making them stronger and more resistant,” explained Hristova. “This oil allows the timber to breathe and keep the smell of freshly cut wood.”
